Description
THIS NOTICE IS A REQUEST FOR INFORMATION TO OBTAIN INFORMATION FOR MARKET RESEARCH PURPOSES. THIS NOTICE IS NOT A REQUEST FOR COMPETITIVE PROPOSALS. ***The National Institute of Standards & Technology, (NIST), is soliciting information for a scanning electron beam research and metrology platform for the new Advanced Metrology Laboratory (AML) currently being constructed. This will be a very specialized instrument. Currently, there is no known commercial instrument that can meet all of NIST's requirements.***The fundamental requirements for this instrument are outlined in this request for information, and manufacturers are invited to provide information relating to their current and future instrumentation relative to these specifications. Final specifications will be determined based on information gathered through this inquiry.***Equipment Name: AML Scanning Electron Beam Research and Metrology Platform; Requesting Office: NIST/ Manufacturing Engineering Laboratory/Precision Engineering Division; Project/Program: Scanning Electron Microscope-based Metrology/Nanometer Scale; Dimensional Metrology.***DESCRIPTION: The AML Scanning Electron Beam Research and Metrology Platform (SEBMP) is a unique reference measurement instrument. This instrument incorporates advanced laser interferometry in the specimen stage to accurately track the X and Y motion of the stage. This instrument will be used for the development and calibration of accurate length metrology reference artifacts and to provide dimensional metrology solutions on samples that can be measured by an electron beam as the probe.***PROGRAMATIC RATIONALE: Scanning Electron Microscopes (SEM) are widely used in U. S. research, development and manufacturing, especially in the fields of nanotechnology and microelectronics where individual device sizes are now approaching few tens of nanometers, but overall sample size is 300 mm or greater. A modern scanning electron beam research and metrology platform is needed for the AML in order to satisfy the NIST customers' needs for length standards on large substrates (silicon wafers and photomasks) and to initiate breakthroughs in accurate metrology using scanned electron beam instrumentation.***Currently, the NIST SEM metrology instrumentation is severely limited by overall specimen dimension. Because of this limitation, larger samples like semiconductor production wafers, 2-dimensional grids and photomasks cannot be measured even if the existing, better than industrial metrology capability would allow the needed measurements. Many NIST customers, therefore, cannot be properly served without damaging or compromising the sample (specimen breakage, sawing or drop-in wafers).***Designed and developed properly, this SEBRMP is more than just an inspection instrument or a metrology tool. This instrument will be a unique instrument, which will enable vast improvement in measurement accuracy and precision on a variety of samples including defects and particles in the nanometer size range.***The Scanning Electron Beam Research and Metrology Platform is an indispensable research instrument, appropriate for the AML. This instrument will be a platform capable of ultra-high resolution imaging, characterization, and dimensional metrology of structures down to a few nanometers. The instrument will be capable of investigating samples as large as whole silicon wafers or phase-shifting photomasks and as small as the samples of nanotechnology research and development (standard stub size). This instrument will be unique in the world and will become a length reference measurement instrument for a whole host of artifacts. Capabilities are planned to include operation at various specimen chamber vacuum levels and “environmental” modes, a wide range of accelerating voltages (electron energies), landing energies and electron energy filtering with magnifications up to 500,000 times and spatial resolution down to 2 nm or better. The instrument will utilize NIST expertise in the development of interferometry for quick nanometer-level and slower picometer-level positioning and measurement accuracy. NIST is and has been developing laser control and data acquisition software for the current KLA/AMRAY SEM Metrology Instrument and that software is available for incorporation into the new instrument. This instrument will employ and exploit the contrast mechanisms advantageous or existing only for nanometer-sized structures. Three-dimensional imaging and metrology will be possible with extensive image processing and analysis, which allows the full use of information generated. It also will have a capability to form, modify and measure in-situ structures a few tens of nanometers in size with the electron beam. It will serve as the platform for accurate dimensional measurements of semiconductor wafers with nanometer structures, and it will be the practical complement to the theoretical modeling work of 2- and 3-dimensional metrology of nano-structures and devices. This instrument will be one of the most important tools used in nanotechnology that advances the measurement science, development, and theoretical modeling of nano-structured materials and devices. ***MINIMUM GENERAL SPECIFICATIONS: ***ELECTRON SOURCE: Field emission gun (thermally assisted FE or cold FE); ***ACCELERATING VOLTAGE RANGE: 100 V to at least 10 kV (30 kV preferred); BEST ACHIEVABLE RESOLUTION: Minimum 2 nm or better (at most advantageous accelerating voltage) ; LOW kV resolution at 500V: 10 nm or better ; DIGITAL IMAGING CAPABILITY: Up to a minimum of 4096 x 4096 pixel resolution (or better) with minimum 16 bit gray scale resolution; BEAM STEERING: plus or minus 20 micrometer beam shift (@10 mm working distance); VARIOUS SCANNING SPEEDS: From slow to high speed, i.e. 80 sec/frame to TV rate; SPOT MODE: Stationary beam or spot mode capability for laser interferometric measurements.
